4 Claims.

This invention relates to improvements in storm windows, and,particularly, storm windows of the permanent self-storing type providedwith an upper glazed sash and a sliding lower glazed sash which may beraised or stored during the summer-time to provide an opening in thelower half of the storm window frame; this opening may be screened witha sliding screened sash, which is adapted to be raised or stored duringthe winter-time, when the lower glazed sash is in use.

It is an advantage of storm windows made according to our invention thatthey may be made of extruded metal, preferably aluminum, having channelor box sections, thereby providing the permanence and strength of metalwhile being lightweight for shipping and handling and economical toproduce. Storm windows made according to our invention are closelyfitting, and may be produced for closer tolerances than has beenheretofore possible with wood or metal storm windows of the self-storingtype.

Because of the close fits necessary to obtain the desirablewind-tightness in storm windows, the so-called self-storing stormwindows heretofore available have not satisfied this need. Such failurehas been attributable largely to the fact that the prior art stormwindows have had to be custom built, i, e. made on special order andfitted on the job in order to compensate or correct for the inevitablewarped, misaligned and/or out-of-plumb construction inevitably found inthe casings of windows in wood or masonry buildings. The carpentry ortinsmith work involved in fitting prior art wood or metal storm windowsnot only was very expensive but could not equal the close-toleranceprecision construction of our windows. Our storm windows may be eithercut and built to stock sizes in the factory or cut, in the factory,shipped, knocked-down, and assembled on or near the site ofinstallation. Though our storm windows are preferably produced in stocksizes, such stock-size storm windows may be easily fitted to the wood ormasonry casing of a window, despite the variations normally found insuch window casings. This substantial advantage is obtained by providingan integral waste strip or flange around the frame of our storm windows.

It is another object and advantage of our storm windows that all thesliding sash may be easily removed for cleaning and such removal may beaccomplished from inside the building on which the storm windows arefitted and permanently mounted. We accomplish this object by providing atiltable sash which may receive the aforesaid sliding sashes and thenmay be tilted to project the bottom portions of said sliding sash intothe room on which the window opens. Except when all said sliding sashesare in a position permitting such removal, the tiltable sash is locked.

It is another object and advantage of our invention to provide a noveladjustable pivot construction for the aforesaid tiltable sash which,after adjustment to fit the tiltable sash precisely in the frame, maythen be permanently and securely locked in its adjusted position.

Another object of this invention is to provide a simple and convenientswingable handle construction permitting the sliding sash to be raisedand lowered in the storm window frame.

A still further object of this invention is to provide a novel cornerconstruction for the sliding sash providing a strong sash corner andsimultaneously providing suflicient flexibility to prevent the glasscarried thereby from being broken during use.

Other and further objects and advantages of this invention will beapparent from the following specification, claims, and drawings, inwhich Fig. 1 is an outside, front elevation of a storm window madeaccording to our invention.

Fig. 2 is a side elevation of the structure shown in Fig. 1, but withthe tiltable sash tilted inwardly and the sill of said sash swung opento a position permitting the sliding sashes carried thereby to beremoved therefrom.

Referring to the drawings, in which lik reference characters refer tolike parts, our storm window is comprised of a frame, referred togenerally by the reference character III. The frame In is comprised of achanneled lintel member II, channeled jamb members I2 and I3, and a sillmember I4, all being preferably formed of extruded or rolled aluminum orlike corrosionresistant metal to provid the strong and rigid box orchannel sections disclosed in the several detail views and discussedbelow. Although the frame members II, I2, I3 and I4 are of a complexc'ross=section, they are formed economically and accurately either bythe extrusion of molten aluminum or like metal through suitableextrusion dies or by rolling the section from coiled strip. Long lengthsof such extruded stock may be cut with hack saws to window lengths,which window lengths may be routed in milling machines wheremodification of the cross-section in certain portions of such windowlengths is required.

Specifically, the lintel H is cut to the window length required fromextruded dee channeled stock of the cross-section shown in Fig. 3B ofthe drawings. Such lintel stock comprises, in crosssection, a bodyportion I I3 having sash-receiving channels III, H2, and H3 and anintegral, outwardly-extending flange or waste-strip I I4 provided withthe parallel break-off grooves II5. In the particular embodiment shown,the ends of the window lengths of the lintel stock are suitably miteredto form the mitered joints with the jambs I2 and I3, as shown.

The jambs I2 and I3 are each formed from lengths of extruded stock ofthe same cross-section, each such window length being mitered at one endto form the mitered joints with the lintel II and the preferred buttjoints with the sill I4. Fig. 11 shows the unmodified cross-sections ofthe jambs in their upper portions I26 and I36. Equivalent cross-sectionsare shown by the combined areas of the portion of the jamb I2 and theportion of the tiltable sash jamb 22 shown in Fig. 4, or the combinedareas of the portion of the jamb I2 and the tiltable sash jamb 22 shownin Fig. 5, or the combined areas of the portion of the jarnb I3 and theportion of the tiltable sash jamb 23 shown in Fig. 6. It will be notedthat the configuration of all of said combined cross-sectional areas isidentical. The jamb I2, therefore, is comprised of a box portion I20having sash receiving channels I2I, I22, and I23 (indicated by dashreference lines in Figs. 4 and 5), and an integral flange of waste-stripI24 provided with parallel break-off grooves I25. The jamb I3 likewisehas a box body I30 having sash receiving channels I3I, I32, and I33 andan integral waste-strip I34 provided with break-off grooves I35.

It should be noted that the waste strips I24 and I34 of the jams I2 andI3 occupy the same relative positions with respect to their sashreceiving channels as the waste strip II4 of the lintel II occupies withrespect to its sash-receiving channels, so that, when the lintel II andjambs I2 and I3 are joined with their respective sashreceiving channelsin alignment, the waste strips I24, I I4, and I34 will form a continuousgrooved fin around the top and sides of the frame III.

The walls defining the channels I22 and I23 of the jamb I2 are milledoff or otherwise removed below the upper portion I26 in order to permitthe frame jamb I2 to receive the jamb 22 of the tiltable sash 2D. Thefront wall I21 of the frame jamb channel I2I is also removed completelyfor a distance below the portion I23 in order to provide a steppedopening I28 for the sealing fin 28 of the tiltable sash jamb 22. Belowthe opening I28, only the rear of the Wall I21 is milled off, therebyproviding a sealing fin I29 on the jamb I2. The jamb I3 is likewisemilled to rovide an opening I38 and a sealing fin I39.

As is evident from the foregoing, the jambs I2 and I3 carry the tiltablesash 20, which is comprised of the channeled jambs 22 and 23 and theswingable sill 24, hinged on the jambs by means of the hinge straps 25pivoted on the jambs 22 and 23. The jamb 22 may be milled out of alength of stock from which the jambs I2 and I3 are formed, butpreferably the jamb 22 is cut from lengths of extruded stock having thecrosssection of the jamb 22 as shown in Fig. 5. The jamb 22 has slidingsash-receiving channels 22I, 222, and 223 corresponding to the channelsI2I, I22, and I23 of the ja'mb I2. The front wall 26 of the channel MIis extruded with a sealing fin 28, but except for the portion receivedin the opening I23 of the jamb I2, the fin 28 and the correspondingportion of the front wall 26 are milled off to permit the jamb 22 to fitand seat in the jamb I2 behind the sealing fin I29, as shown in Fig. 4.The tiltable sash jamb 23 is likewise provided with a sealing fin 29adapted to be received in the opening I38 and is milled to seat behindthe fin I39 of the jamb I3. The jamb 23, being of a similarconfiguration as jamb 22, is also provided with sash-receiving channels23I, 232, and 233 which normally align with the corresponding channelsI3I, I32, and I33 of the jamb I3.

The sash 20 is pivoted in the jambs I2 and I3 by means of the pivots 30.The tops of the jambs 22 and 23 are cut on an angle (which mates withthe bottom of the upper portions I26 and I36 of the jambs I2 and I3)which permits the sash 20 to pivot only from an aligned position in theframe ID to a position in which the top of the sash 20 is swungoutwardly and the bottom is swung inwardly, as shown in Fig. 2. Thepivots 30 are comprised of hardened steel bushings 3| and pivot disks 32provided with eccentric bosses 33, as shown in Fig. 6. The bushings 3Iare received in suitable sockets drilled in the jambs I2 and I3 at thecenter of the steps of the openings I28 and I38. The pivot disks 32 arereceived in shallow sockets drilled in the back of the jambs 22 and 23.The edges of these sockets are then spun over to hold the pivot disks 32rotatably in the sockets. I

Although the jambs I2, I3, 22, and 23 are preferably milled in suitablejigs to maintain uniformity, in actual production, variations from pieceto piece and accumulation of deviations within permissible productiontolerances will not insure that the tiltable sash 20 will always fitprecisely in the frame I0, nor will the sliding sash receiving channelsof the several jambs always align precisely immediately upon assembly,if the pivots 30 were not adjustable. To adjust the pivots 30 so thatthe sash 20 will fit and swing properly in the frame III, the pivotdisks 32 are simply rotated in their sockets until the eccentricity ofthe bosses 33, rotating in the bushings 3I throws the sash 20 intoproper position in the frame III.

To look the pivots 30 in their adjusted position, the pivot disks 32 areprovided with a plurality of tabs 34 spaced about the periphery of thedisks 32 so that in any adjusted position, at least one of the tabs willbe located over a channel wall in the jamb carrying the disk. With thedisk 32 rotated to its adjusted position, the tabs 34 are driveninwardly to rivet at least one in the deel iaS sections of metalprovided by the channel wa With the sash 20 mounted in the jambs I2 andI3, the sliding glazed sashes 40 and 50 and the sliding screened sash 60are slid into the channels of the jambs, the two glazed sashes beingadjacent each other and the screened sash preferably being in the innerchannels. The sill 24 may then be swung to its normal position closingthe end of the jambs 22 and 23.

Figure 3 shows that the sill 24 is comprised of a length of extrudedstock having a substantially box section and comprised of a sill portion240 having a beveled sealing ridge 24I which, with the ridge 242,defines a screened sashreceiving channel 243. The sill portion 240carries a dependent sealing fin 244 and a seating fin 245.

As a final assembly operation, the sill I4 is joined to the jambs I2 andI3. The sill I4 comprises a hollow body or box portion I40 having aslotadapted to receive a rubber sealing strip I M which engages theseating fin 245. The body portion I40 carries a sealing fin I42 which isengaged by the fin 244 of the sill 24. The body portion I40 also carriesthe integral waste strip I 44 provided with break-off grooves I45. Thelength of the extruded stock from which the sill I4 is cut is milled atthe ends topermit the body portion I40 to be received between the jambsI2 and I3 and the waste strip I44 is notched, as shown in Fig. 1, toreceive the ends of the jambs I2 and I3. The notches in the thin wastestrip I44 are easily trimmed, as by filing, to compensate for anyaccumulation of manufacturing tolerance and to permit the sill I4 toseat firmly on the seating fin 245 of the sill 24.

The glazed sliding sash 40 is comprised of a frame of extruded metalstock 4I having a deep glass-receiving channel 42 in which the light 43is received, being supported and sealed therein by means of thecompressed rubber glazing channels 44. The glazed sliding sash 5B issimilar to the sash 4!], except that this embodiment is shown with abottom member 5| provided with a circular groove 52 adapted to receive aswinging handle III as may be seen in Figure 3; the member 5| is alsoprovided with a weather-stripping groove 53 adapted toseat on thebeveled ridge 24I of the sill 24 when the sash 50 is in its loweredposition.

The screened sliding sash 60 is comprised of a frame of extruded stockhaving a cross-section as shown in Figs. 3A and 3B and provided with aninwardly opening channel SI in which the screening 62 may be locked bythe locking wire 63. The bottom member of the frame of the sash 60 isalso provided with a groove 64 adapted to receive a swinging handle III.

The handles I0 are hinged very simply in the sliding sashes. The handlesI0 are punched out of extruded stock having a cross-section similar tothat of the end views of the handles as shown in Figs. 3 and 3A. Bypunching out a center area bounded by the hinge pin portion II, thestraps I2 and the grip portion I3, and simultaneously punching away anarea bounded by the hinge pin portion, the straps I2 and the ends of thelength of stock, a handle III, as shown in Fig. 8, is formed. To mountthe handle in the sash, strap-receiving slots I4 are milled across thehandle receiving grooves in the sashes. The hinge pin portions of thehandles are then fitted in the receiving grooves and slid in from an endof the sash frame until the straps can fall in the slots I4; then theedges of the groove are peened over to lock the handles in place alongthe length of the groove. The handles are then free to swing from adependent position, as shown in Fig. 3A to a raised position, as shownin Fig. 3.

To hold the several sashes frictionally in their raised positions andalso to press the sashes against the forward walls of the sash-receivingchannels in order to seal the tolerance allowed between the sash andchannels and to prevent rattling, the portions of the sash framessliding in the channels are grooved to receive leaf-spring wires 85, asshown in Figs. 4 and 5.

A very simple and novel corner construction for the sliding sashes isshown in Figs. 9 and 10. The frame members fit with a mitered joint, asshown, one member being drilled and countersunk to permit a screw toextend into the channel of the other frame member. The walls of theother member are slotted to receive a nut 5| which receives the screw90. Tightening the screw 9i jams the mitered surfaces together and anytendency to spring the joint is resisted by the tensile strength of thescrew. At the same time, the screw does not prevent one frame memberfrom pivoting with respect to the other and thereby providing a flexibleframe. It has been discovered that such a flexible frame reducesbreakage of the glass which may be mounted in it due to sudden shocks,the rubber glazing strips permitting slight movement of the glass in theframe. The flexible corner construction permits the glass to flex andfiex other portions of the frame when one corner or portion of the frameis distorted. It has been found that a rigid corner construction willhold the glass rigidly and, thereby, increase the danger of glassbreakage.

Operation Storm windows constructed and assembled as above described arepreferably made up in stock sizes in which the width of the tilting sash20 is somewhat less than the sash opening of the window on which it isto be mounted. This is to permit sash 28 to tilt into the room on whichthe room Window opens. The proportions of the several waste strips I24and I34 are then such that their total width will exceed the width ofthe opening between the casing jambs in any stock window casings. Theheight of a storm window is also selected that the waste strips H4 andI44 will exceed the height of the opening between the sill and th lintelof the window casing. To fit the storm window, all that need be done isto break off the waste strips along the break-off grooves I I5, I25,I35, and I45 until waste strips fit against the blind stops of thecasing. The Waste strips are then drilled and screwed to the casing.

When mounted and employed as a storm window to insulate the room window,the sliding sash 40 is raised and the sash 50 is lowered, and thescreened sash is raised or stored, as shown in Figs. 1, 3A and 3B. Forsummer use, the sash 50 is simply raised or stored and the screened sash50 is lowered. It will be noted that the parting line between the upperportions I26 and I36 of the jambs l2 and i3 and the tiltable sash 28 isabove the bottom of the sash Thus, the height of each sliding sash beinggreater than the height of the upper portions of the jambs l2 and 53,when any one of the sashes is raised, the tiltable sash is automaticallylocked against tilting.

To remove the sliding sashes for washing, all sashes are lowered intothe tiltable sash 20, care being taken to swing the handles it upwardly.The tiltable sash 29 may then be tilted and the sill 24 swung open, asshown in Fig. 2, to permit the sliding sashes to be removed into theroom on which the window opens.
